Two way sync - potential solution

Actual behaviour:

• Files created in a folder which has been previously marked ad "available offline" are not automatically uploaded

Expected behaviour:

• 2way sync (as mentioned in: #1663, #1683, #1437, and #960)
  Any file created in that folder should be automatically uploaded.

Potential temporary solution:

A free third-party app Tasker (https://tasker.dinglisch.net/) is capable of: 1) running a background service monitoring changes in files and folder, 2) sending different types of intents.

1. Would it be possible to send an intent to the ownCloud client forcing upload of a single file?
2. What is the intent and syntax of the additional data that needs to be provided for a successful request (I assume at least the local path to the file). After brief analysis of the code I found this: com.owncloud.android.files.services.FileUploader, but I am not sure if this is the correct one.

Start by reviewing com.owncloud.android.files.services.FileUploader and the related issues #1663, #1683, #1437, and #960. Determine whether the requested two-way sync behavior or a Tasker-triggered single-file upload is in scope; completion would require a clearly defined request, intent data syntax, and upload behavior.
